With the popularity of the Internet, text messaging has become an indispensable part of people's daily lives. We use text messages in various situations, such as registering accounts, confirming orders, retrieving passwords, verifying verification codes, etc. Among them, SMS verification code verification is currently one of the most commonly used methods. In the process of implementing SMS verification code verification, the implementation of the SMS sending interface is particularly important. So, this article will introduce how to implement the mobile phone SMS interface to send text messages in PHP.

  1. What is the SMS interface

The SMS interface, simply put, allows your program to send text messages to the mobile phone through the API interface. In order to avoid the nuisance of a large number of malicious text messages and advertising text messages, mobile phone communication companies have opened this interface to allow legal manufacturers to become their partners. With the help of their technology platform, legal text message senders can send text messages to mobile phone users. .

  1. Introduction to the implementation principle of the SMS interface

The implementation principle of the SMS interface is:

(1) The caller of the SMS interface submits an SMS sending request to SMS platform.

(2) After receiving the request, the SMS platform parses out the mobile phone number and SMS content, and then passes the SMS content to the operator's SMS center.

(3) The operator's SMS center delivers SMS content to the mobile phone through the SMS channel.

(4) The mobile phone receives the text message and displays it.

  1. Steps to implement SMS interface in PHP

(1) Register an account on the SMS service platform and activate the service.

(2) Create an application in the SMS service platform and obtain the App Key and App Secret of the application.

(3) Use the PHP programming language to write a program to implement the function of sending requests to the SMS platform, and send the SMS sending request to the SMS platform.

(4) After receiving the request, the SMS platform parses the request parameters and sends the SMS sending request to the operator's SMS center.

(5) After receiving the request, the operator's SMS center will send the SMS to the mobile phone user.

  1. PHP code implementation for sending text messages

In PHP, sending text messages requires the use of the cURL library, which can be achieved through the following code:

/**
 * 发送验证码短信
 * @param  string $mobile 手机号
 * @param  string $code   验证码
 * @return array          发送结果
 */
function send_sms($mobile, $code) {
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, "http://api.sms.com/sms/gateway/send");
    curl_setopt($curl, CURLOPT_POST, true);
    curl_setopt($curl, CURLOPT_POSTFIELDS, array(
        'mobile' => $mobile,
        'content' => "您的验证码是{$code},有效期30分钟。",
        'apikey' => "your_api_key"
    ));
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    $response = json_decode(curl_exec($curl), true);
    curl_close($curl);
    return $response;
}
Copy after login

above In the code, we use the cURL library to send a POST request and pass the request parameters to the interface in the form of an associative array. Among them, the API Key needs to be replaced with the API Key of the application you created in the SMS service platform.

  1. Summary
